14kt gold-filled. Measures 1" in length. Made of 22 gauge wire. Head pins are wires that feature a flattened end designed to hold a bead in place at the end of the wire. The excess wire can then be made into a simple loop or wire wrapped loop and added as embellishment to earrings, the end of a necklace, or even act as a centerpiece. The 22 gauge wire fits most glass, crystal and metal beads. This wire is sturdy and withstands daily wear and tear. Sold individually.
